This visualization displays the top 10 countries by deaths from air pollution in 2020, using a pie chart where each slice represents a country’s death count. The chart is rendered as an SVG using D3 v5, with data fetched from a CSV URL. The code uses `d3.pie` and `d3.arc` to generate the slices, while `d3.scaleOrdinal` assigns colors. Text labels show death counts in thousands, and a legend lists each country with its corresponding color and value.
